Series 830/840/860 Instruction ManualAppendix AAppendix A Conversion Formulas and Gas TablesConversion of Flow Rate to Other T and P ConditionsThe flow rate of your transducer is referenced to certain “standard”conditions of temperature and pressure. Unless otherwise specifiedin your order, these standard conditions are 21°C (70°F) and 760 mmof mercury (1 atmosphere). If you wish to convert to other “standard”conditions or to find the “actual” conditions in the pipe whereyour instrument is installed, use the following relationship:P 1 T 2Q 2 = Q 1 (1)P 2 T 1( ) 1 = The standard conditions under which your instrumentwas calibrated,( ) 2 = The new standard conditions or the actual temperatureand pressure conditions in the pipe,Q 1 =Q 2 =P =The gas mass flow rate referenced to the calibrated standardconditions (sccm or slm),The gas mass flow rate referenced to the new standard oractual conditions (sccm or slm—“S” means “standard,”accm or alm—“A” means “actual”),Absolute pressure (kg/cm 2 or psia), andT = Absolute temperature (°K or °R) (°K = °C + 273, °R = °F + 460).Example 1: Changing “Standard” ConditionsIf your transducer has a flow rate reading of 10.00 slm and was calibratedat standard conditions of 70°F (21°C) and 1 atmosphere (14.7psia), and if you wish to convert this reading to standard conditions of32°F (0°C) and 1 atmosphere, then you would use Equation (1) as follows:Q 2 =14.7 460 + 3214.7 460 + 70(10.0) = 9.28 slmThe flow rate referenced to 0°C will be approximately 7% lower thanwhen referenced to standard conditions of 21°C.Example 2: Finding the “Actual” Flow RateIf the flow rate and calibrated standard conditions are as given inExample 1 and you wish to find the actual flow rate at 100°F and30 psig, then you would use Equation (1) as follows:IM-83/84/86-H A-1
